DRUM TUBULAR SECTIONAL STOVE.

SPECIFICATION forming part of Letters Patent No. 456,960, dated August 4, 1891.

Application iiled October 23, 1890 Serial No. 369,073. (No model.)

.To all whom it may concern:

Be it known that we, GEORGE E. LEONARD, of the city of Menominee, in the county of Menominee and State of Michigan, and SILAS A. STOWE, of Neenah, in the county of Vinnebago and State of Wisconsin, both citizens of the United States, have invented a new and Improved Drum Tubular Sectional Stove, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure 1 is a vertical transverse section of our improved stove. Fig. 2 is a horizontal section taken on the line 2 2 in Fig. 1, and Fig is a horizontal section taken on the line 3 3 in Fig. l.

The object of our invention is toconstruct a stove with an increased and variable radi- The invention consists in the particular construction and arrangement of parts` as hereinafter fully described, and pointed out in the claims.

The stove-body A, consisting of a drum tubular section, is furnished with a fire-pot A2, which is provided with the grate B and ash-pit C. The drum tubular section is provided with an enlarged upper portion D and a smokechainber E below the 4ash-pit. The enlarged part D communicates with the smoke-chamber E through one or more pipes a. The top of the body A communicates with the drum 'F through the pipe-section G, and the said pipe-section is provided with a damper b, by which direct communication between the drum F and the body of the stove may be closed, thus causing the products of combustion to prss downward through the pipe or pipes a into the smoke-chainber E,

i thence through the flue e, the vertical pipe d, and flue e to the pipe G, whence it passes upward through the drum F. The drum F consists of a central pipe H, having hollow heads g g', attached to opposite ends, the lower head g communicating with the pipe G and the upper hollow head g communicating with the smoke-pipe h. A damper/L' is placed in the pipe H, and the hollow heads g g are connected by pipes j. Then the damperrl is closed and the damper b is closed, the products of combustion pass downwardly,

as before described, and when they reach the pipe G they pass upwardly through the pipes j to the smoke-pipe h. Vhen the damper i is open, the products of combustion pass from the pipe G through the pipes H j. Then the damper fi is closed and the damper b is open, the products of combustion pass directly through the pipe G to the hollow head g, thence upward through the pipes j to the hollow head g, thence directly to the pipe h. When both of the dampers t' b are open, the draft is direct through the pipes G H h.

The fire-pot A2 is provided with a feeddoor A and a draft-door B. The ash-pit O is furnished with a draft and ash-door O', and the space E is furnished with a cleaningdoor E. It willbe observed that the pipes a surround and incase the fire-pot, thus increasing the radiating-surface, also improving the air circulation at the surface of the firepot. p

Having thus fully described `our invention, we claim as new and desire to secure by Letters Patent l. In a stove, the combination, with the stove-body A,provided with the enlarged top D, and the smoke-chamber E below the ash pit and having the fiue e and tubes a connecting the enlarged top and smoke-chamber, of the pipe-section G, secured to the top D and provided with the'damper b and the flue e', and the vertical pipe d, connecting the fines e e', substantially as described.

2. In a stove, the combination, with the drum F, provided with the damper if, of the stovebody A, provided with the enlarged top D, the smoke-chamber E, having the flue c andf the tubes a, connecting the top D and chamber E, the pipe-section G, connecting the stove-body and drum together and provided with the damper ZJ and thev flue c', and the pipe el, connecting the fines c e', substantially as herein shown and described. v
